Hibernate的拦截器与监听器

定义监听器并继承SaveOrUpdateEventListener接口

package dao;

import org.hibernate.HibernateException;
import org.hibernate.event.SaveOrUpdateEvent;
import org.hibernate.event.SaveOrUpdateEventListener;

import domain.User;

public class SaveListener implements SaveOrUpdateEventListener {

	public void onSaveOrUpdate(SaveOrUpdateEvent event)
			throws HibernateException {
		
         if(event.getObject() instanceof domain.User){
        	 User user = (User)event.getObject();
        	 System.out.println(user.getName().getFirstName());
         }
	}

}

 配置：在hibernate.cfg.xml中配置

	<event type="save">
		<listener class="dao.SaveListener"/>
		<listener class="org.hibernate.event.def.DefaultSaveOrUpdateEventListener"/>
		</event>
	</session-factory>
</hibernate-configuration>
